Secret Reconstruction Protocol Based on Smart Contract

The secret reconstruction protocol for a verifiable secret sharing scheme is designed.Under real-life conditions where the participants are all rational,the punishment mechanism and the method of deducting the deposit are used to conduct the behavior of malicious parties verified by the verifiable secret sharing scheme Constraint,and using the tool of blockchain smart contract,according to the independence and non-tampering of smart contract,the problem of trusted third parties that are difficult to solve in previous research is solved.The protocol is divided into two parts,local protocol and smart contract.While ensuring the security and confidentiality,the protocol can also utilize the design of smart contracts to achieve fairness.
